That looks like bad data in the file.
Do you have a test file that shows the problem?

yes, I have the file that I was trying to import, when I encountered this error. The file could have a problem. But blender should trap error better?
Do you have a location I could upload this file ? the file is this large: 417763005 google drive work?

Ill leave this open for a little while

https://drive.google.com/drive/folders/1EiARC6gSX2HpEQ4dsAtjh-1C-i-AWnpk?usp=sharing

work flow :

gimp(token.png -> token.xcf -> token-bw.png)
openscad(token-bw.png -> token-bw.scad -> token-bw.stl)
then wanted to decimate/ simplify with blender...

Yep, that file is corrupted somehow, lots of unexpected weird ASCII keycodes here… Not much we can do am afraid.
